Alton Towers operator Merlin Attractions has been fined £5 million at Stafford Crown Court after admitting health and safety breaches over The Smiler rollercoaster crash.
The crash left two teenagers needing leg amputations, and several other victims with serious injuries.
Several victims of the crash were in court, where the hearing was told the force of the rash was equivalent to a family car crashing at 90mph.
The chief executive of Merlin Entertainments has said the company had "let people down with devastating consequences" after last year's Smiler rollercoaster crash at Alton Towers.
In a statement outside Stafford Crown Court, where the company was fined £5 million for health and safety failings, Nick Varney said: "From the beginning the company has accepted full responsibility for the terrible accident at Alton Towers and has made sincere and heartfelt apologies to those who were injured.
"In accepting responsibility and liability very early on we have tried to make the healing and compensation process as trouble free as possible for all of those involved.
"We have strived to fulfil our promise to support them in every way and I promise that this support will continue as long as they need it.
"We were always aware that we would end up here today facing a substantial penalty, as has been delivered by the court today. (But) the far greater punishment for all of us is knowing that on this occasion we let people down with devastating consequences.
"It is something we will never forget and it is something we are utterly determined will never be repeated."
A video showing the moment a carriage on the Smiler rollercoaster at Alton Towers crashed into an empty car has been shown in court.
Merlin, the operator of the park, has been told it should expect a "very large fine" for breaching health and safety.
